Specification of Letters Patent,

Patented March 16, 1909.

. Be it known that I, THEononE AUoUsiUs ErsEN, of the city of Los Angeles, in the county of LosAngeles, in the State of -Cali' fornia, have invented certain-new and useful Improvements in the Construction of'Buildings, of which the following is .a full, clear, and exact specification, reference being had to the annexed drawings, and-to the letters and-figures-marked thereon. c

This inventlon which relates to ,1mp rov6 ments in the construction of buildings has especial reference to buildings composed of reinforced concrete-and it maybe applied to -buildings of -steel or wooden construction with the same advantage which attach by the use thereof. to buildings of reinforced I concrete.

A nong the objects which this invention achieves, there is one in particular which it is principallyintended tolsubserve', namely,

to provide a buildin having one or more stories and so that it shall be sufiiciently elastic in its constitution that it,.will" yield sufficiently and elastically to withstand a severe tendency to disturbor injure it, such as the tendency of anearthquake, while 'as distinct from an entirely rigid structure, which because of its rigidity, is. liable to de-x struction from earthquakes and other forms of volcanic earth-tremors; the blows or tremors -from ,earthquakes," or other volcanic disturbances are taken up by the elastic structure which my invention in its completeness consistsof, and are by reason of that elasticity distributed throughout the structurewithout doing injury thereto,

My invention consists in respect of the columnar parts thereof, and. the meansof supporting the floors of the buildingsattached to the columnar parts thereof, of cantaliver platforms, which may be of any convenient size, and which as an ex'ample of whatlintend to be'understood as using, have a" length and-breadth or diameter of about ten lineal feet, wherein the space be-' tween. centers of columns is about twenty feet. 7

I construct the columns in such manner that each of said columns will carry one of the cantaliver platforms at aheight corre- .sponding with the several distances between e floors and ceilings of the successive apartments or divislons of the buildings. In constructmg the columns. and cantastructed. 1 According tomyinvention, when the colliver platforms, the columns and cantaliver platforms may be made so that the columns and cantaliverplatforms are separated from each other, in which case the lower ends of the columns pass and fit snugly into a corre spondingly shaped" hole in the center of the top of the-cantaliver platform, while the upper end of each column is so formed asto fit into the hole at the center of the bottom of the eantaliver platform.' It is not, how:

ever, necessary to construct the columns and "cantaliver platforms in separate sections in the manner hereinbe'fore stated, asthe' colm nus and cantaliver platforms may be'cast monolithically in concrete, in molds-so that each column has all the cantaliver platforms ineach of such structuralconstituents of the building. In thecase of using cast iron as the material for thecolumns and cantal-iver platforms, they also may be cast in molds in one-piece, and in the case of riveted, latticed.

or gusset plating methods of constructing to say, of pieces of steelor iron riveted, to-

getherin the manner commonly practiced,- and having the cantaliver platforms riveted to the columns, or made separate from the columns, while havin a hole in the center to receive the upper and lower ends of the sections of columns respectively, as these have been herein described, in the case of using concrete as the'materialof which said colnuns and cantaliver platforms are concolumnsand canta-liven platforms, these parts may be similarlyformed alike, that isnmns and 'c'antaliver platforms :are erected, I

' platforms united with the columns exist on every floor of the structure. While the structure is thus very strongly supported at the floors it is at the same timean elastic structure .in which the loadupon any floor is capable of having its stress widely distributed over a large'floor area, and the structurc being elastic, therefore distributes throughout the building, earthquake and other volcanic disturbances which would tend to destroy the same, if suchelasticity as this invention permits of were omitted, such thrust, for example, with horizontal and ver- 5 tical components, which are so well known to produce destruction in altogether rigid structures, when subject an earthquake shock or volcanic disturbance.

U on the annexed drawings, Figure 1, is

an e evation with certain parts in section, of a portion of a building having several floors, one above the other constructed in accordance with my invention, showing forms of applying the cantaliver .platforms IiPOIl the vertical columns of the structure. ig. 2, is a vertical section upon the line a, a, Figs. 6,

9, and 12. Fig. 3, 1s an inverted plan of one of the cantaliver platforms shown at Figs. 1, and 2. Fig. 4, is a plan of the top' of one of the cantaliver platforms. ,Fig. 5, is a perspective view on an enlarged scale of parts a of two of the edges of a cantaliver platform showing a well known form of hanger resting thereon, for carrying the girders or joists of the floor between the cantaliver platforms. Fig. 6, is a plan of four columns, four cantaliver platforms, and showing a methodof supporting a floor thereon by han ers. Fig.

7, 1s a vertical section on the line h, Fig. 6.

Fig. 8, is another vertical section. on the line 0, c, F'g. 6. Fig. 9, is another plan of four columns, four cantaliver platforms, and flooring attached thereto, in a slightly different manner from that shown in Figs. 7, and 8.

Fig. 10, is a section on the line d, d, Fig. 9. Fig. 11, is a transverse section on the line e, c, Fig. 9. Fig. 12, is a plan in which the joists or girders constituting the floor are in part supported uponthe flat tops of the canta- 40 liver platforms, and also artlyu on what I prefer to call static gir ers. ig. 13, is a transverse section upon the line f, f, Fig. 12.

Fig. 14, is a transverse section upon the line g, g, Fig. 12. Fig. 15, is a transverse section through one of the side or end walls of a building, wherein the columns and cantaliver platforms are placed throughout the in- .terior of a building 1n the manner correspondmg to my present invention, it bein explained that in the side or end of a bu' ding j opposite to that shown in Fig. 15, the half cant aliver platforms proj ecting from the walls thereof necessarily project in opposite directions, that is to say, always toward the interior of the building, and always in line and level with the other cantaliver carrying the several floors. As'shownb y Figs. 1, 2, 6, 7, 8, 9, 10, 11,

I 12, 13, and 14., the vertical the load upon the floors of the structure are supported from floor to floor by means of the co umns A, A, A A etc. In cases where the columns are made in several pieces the bottom of the column is held in 'a recess in the center of the foundation block B. as

platforms to the influence of describe.

components of shown more particularlyin section in Fig. 2. At the up er end of the lower column A, as shown by igs. 1, and 2,.the cantaliver platform C, is carried, said column being formed with its upper portion of a diameter to fit into a hole in the center of the cantaliver platform C, the column A, at its upper end. preferably having a projecting flange portion D, for giving horizontal support to the bottom of the cantaliver platform C. The

cantaliver platform C, is of such depth that when the upper portion of the column A, is placed'withm the hole E, in the center of the cantaliver latform C, the next section of column A, has its base laced within the up- '80 per part of said central ole as shown at Fig.

2. In the same manner a second cantaliver platform 0, is carried upon the top of the second column A, and a third column A .is similarly carried in the hole E in the center of the second cantaliver platform'C k In the same manner the third cantaliver platform C is carried upon the upper end of the third column A and a fourth column A is carried: in the same manner in the hole EZ'in the upper part of the third cantaliver platform 0 i and so on for any number of columns and cantaliver latforms extending through the vertical height of a building. WVhen the interior of a-bu-ilding has the col- .95 umns erected within it, in their pro er num-. her and positions as hereinbefore escribed, then the cantaliver platforms are united to each other by the flooring-placed on top of the beams or joists which may be of any-suit- 1'00 able kind, examples of which I hereinafter- Before, however, that the building is in the condition for receiving the floorings, cantaliver latforms, corre'sponding'to the cantaliver patforms C, hereinbefore described and shown upon the annexed drawings, are correspondingly placed in the walls of the building as shown at Fig. 15, that is to say, they are either built into the walls of the building as shown at, F, or in the case of a building whose walls are of concrete they maly be constructed in one piece with the wa ls. The upper face of each cantaliver platform isfla't and level, and by preference 1s of rectangular form, such for example as the square indicating the top of theplatform in Fig. 4, or it may have two of its opposite sides of g eater or less length than the two other sides at right angles thereto.

The perspective view Fig. 5, shows an ord'- nary iron or steel hanger G, as placed in posle tion on the edge of one of the cantaliver platforms C, in position toreceive a transverse beam or'joist, such as the beams or joists marked H, in Figs. 7, and 8. The beams or joists H, may be placed to lie at right angles to each other in the same floor, so that the ends of eachof the beams or joists H, rest upon the hangers G, a number of such hangers corresponding to the number. of such I;

-necessary and for the beams or (jioists being placed so .as to be either suspende from or resting upon the upper edge or face of each-cantaliver platform.

In Fig. 6, the flat palms or upper ends of the hangers G, are shown as restlng and sup ported upon eachof' the four sides of each cantaliver'platform, and for the purpose of supporting those beamsor joists whose ends do not rest directly upon the cantaliver platforms I insert what I designate a trimmer K toward the. end of the two ad'acent faces of the cantaliver platforms. he beams or ioists stretching from cantaliver platform to '{eantahver platform may be covered and smoothed over with cement, or any other .suitable flooring material.

In place of using hangers of the kind marked G, in Fig. 5, and in other figures of drawings, I may use any other suitable kind of hanger of which there are several different forms and shapes manufactured, the hanger in itself constituting no part-of my present invent on, and I may use beams or joists of any suitable transverse sectionfor stretching between the several cantaliver platforms .of

my improved building structure. When ur ose of imparting greater stiffness to the ui ding, and for distributing the floorload also which may be more heavily concentrated at some parts of a floor than at other parts, I use what-I designate a static beam' as shown at K, Figs. 1,

2, 12, and 15, that is to say, a beanrwhich stretches entirely across two or more. of the cantaliver platforms, that is to sa from column to column,-and which is 'he d down thereto by dowels L, as shown at Fig. 2, fastened into, and projecting upward from the upper flat top of the cantaliver platform and provided with screw nutsfor holding down the said beamsto each of the said-platforms, either firmly or with any degree of yielding compatible with the'design of the bui ding.

When constructing a column with a series I of cantaliver platforms monolithically arranged thereon in the mannerv hereinbefore described, of reinforced concrete, that is to say, a'column with several cantaliver platforms thereon, I construct the same by ouring concrete into a mold wherein the co umn liver platforms, said beams or joists stretching from cantaliver platform to cantaliver platform throughout the structure.

2.- he combination of columns, cant'alive'r latforms forming part of the floors of a uilding centrally supported u on said col umns, cantaliver platforms in t e walls of a building, the parts of the floor between said cantaliver platforms being constructed of beams and joists whose'ends are supported byhangers carried upon the edges of the cantali-ver platforms, said beams and joists stretching from cantaliver to cantaliver throughout the structure:

In testimony whereof ';I I M my hand and seal at the city of Los nng les aforesaid, in'the presence of two subscribing witnesses. I
